2 Claims. 1 This is a division of my co-pending application Serial No. 155,110, filed April 10, 1950, now Patent No. 2,643,096 issued June 16, 1953.

This invention relates to improvements in narrow ware looms and it is the general object of the invention to provide improved means formounting the cloth roll supporting shafts so they may be readily applied to and removed from the loom.

Many narrow ware looms attain such a length as to make desirable intermediate supports or frames between the loomsides for the take-up and cloth roll mechanisms.- In such looms the cloth rolls are ordinarily mounted on several aligned shafts which are supported by bearings carried by the intermediate frames, but in the past these intermediate bearings have been of complicated construction involving several parts and necessitating considerable labor to remove the shaft sections for the purpose of unwinding the cloth and then returning the shaft sections to the loom.

It is an important object of the present invention to provide a bearing for two adjacent ends of cloth roll shafts mounted on an intermediate support or frame and held in position against endwise motion relative to the shafts by a single retaining means carried by the intermediate frame. The bearings preferably have non-circular frustro-pyramidal cups or the like to receive similarly formed ends or gudgeons of the shaft sections, and the cups are so formed as to free their gudgeons readily when the opposite end of the shaft is swung forwardly.

The cloth rolls of narrow ware looms may either be loose on their supporting shaft and be turned by a belt or the like turned from a loom shaft, or they may be equipped with a friction drive for their supporting shafts to be turned as the latter arerotated. When the latter manner of driving the cloth rolls is utilized in a gearing mechanism is employed at each end of the loom and half of the aligned shafts are driven from one end and the other half from the opposite end. It is a further object of the invention to mount the adjacent ends of shafts driven from opposite ends of the loom in a central bearing made of two saddle or bearing parts which are alike, one part for each shaft end, and clamp the two parts together and to an intermediate frame. In carrying out this feature of the invention each half or part of the central bearing will have a gudgeon rotatable in the center intermediate frame and another part formed as an open slot bearing to permit forward removal of the asso- 'ciated shaft.

I to a cloth roll 22.

With these and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts hereinafter described and set forth.

In the accompanying drawings, wherein a convenient embodiment of the invention is set forth,

Fig. 5 is a horizontal detail section on line 5-5, Fig.

Fig. 6 is an enlarged horizontal section on line 6--6, Fig. 1, showing a hearing so constructed as to afford driving relation between the adjacent ends of two cloth roll shafts, and

Figs. 7 and 8 are vertical sections on lines '!--l and t8, respectively, of Fig. 6.

Referring particularly to Fig. l, the loom has at the ends thereof primary loom frames Ill between Which are located five intermediate frames H-lS. These frames may be held in fixed position in any approved manner as is customary in the manufacture of narrow ware looms of considerable width.

Each of the several webs or fabrics 20 is wrapped around a take-up roll 2i and then leads As indicated in Fig. 1, the loom is considered as being divided transversely into four sections I, II, III and IV, and the cloth rollsof these sections are mounted on cloth roll shafts 25, 25, 21 and 28, respectively. These shafts are aligned lengthwise of the loom and the cloth rolls are driven frictionally by their respective shafts and tend always to turn a little faster than is required to take up the cloth deliverecl to them by their take-up rolls.

The loom has two take-up mechanisms at and 3| located respectively at the left and right ends thereof which drive gears 32 and 33, respectively. Gear 32 is secured to shaft 25 and gear 33 is secured to shaft 23.

As shown in Fig. 4 the shaft 28 has secured thereto a collar 35 which engages the inner or left end as viewed in Fig. 1 of a bearing 36 on frame I5 having upper and lower arms 3? and 33 which define between them a forwardly opening slot bearing 39 for shaft 28. The latter extends through thebflarinEfiIDt 3 9 so that the gear 33 may be attached thereto, and is normally held in the position shown in Fig. 4 by a removable pin 40 passing down through the arms 31 and 3B in front of the shaft 28. When it is desired to move the right end of shaft 28 forwardly the pin 4c is removed and the shaft swung in a frontward direction out of the slot 39.

It is desirable that shaft 28 be able to drive shaft 21 and means for accomplishing this result is shown in Figs. 6, 7 and 8, where it will be seen that a bearing member 45 having a cylindrical periphery it fits into a hole or bearing 4! in the intermediate frame or support 14. This bearing has oppositely opening bearing cups 48 and 49, respectively, which are preferably frusto-pyrarnidal to receive similarly formed gud'geons 50 and ti on the shaft sections as and 27, respectively.

A guide member or positioning screw 52 is tapped through the forward part of the intermediate frame i4 and extends into a groove 53 formed peripherally in the bearing 45 to limit motion of the latter transversely of the frame l4 and longitudinally of the adjacent shaft sections. The bearings cups 4!; and 4e are coaxial so that the shaft sections 2'. and 23 are held with their axes aligned.

When the right end of shaft 28 is moved forwardly in slot as as already described the gudgeon t because of its shape will be able to unseat itself readily from its bearing 48 in the collar 45 without cramping and without subjecting the collar to any strain which might break it. Likewise, after the cloth has been removed from the rolls 22 the shaft is can be replaced first by inserting its gudgeon Sill into the bearing 48 and then moving it endwise to the left, Fig. 1, until the collar 35 is against the intermediate frame i5, after which the shaft will be inserted into its end bearing and pin All replaced.

The left end of shaft 25 and the adjacent ends of this shaft and shaft 25 may be mounted in a manner similar to that already described for the shaft sections 2? and 28. The two aligned shafts 2? and 28 will be driven by gear 33, and in like manner the aligned shaft sections 25 and 26 will be driven by gear 32.

The adjacent ends of shafts 26 and 21 are mounted for rotation as shown in Figs. 2 and 3'. The intermediate frame l3 has drilled there through a hole 69 serving as a bearing for shaft supports or saddle bearings 55 and 52, see Fig. 3, which collectively may be considered as a central bearing. The two saddles BI and 62 are alike but will be described as two separate parts. The saddles El and 62 have slot bearings 63 and 64, respectively, opening forwardly for reception of their associated shaft sections and saddle 6| has a gudgeon 85 extending into one side of bearing 60 and saddle 52 has a gudgeon 66 fitting into the other side of the bearing.

The gudgeons 65 and 65' have parallel walls 6! and iii respectively, extending along one side of their respective slots 53 and 64. A clam-ping screw 69 extends through wall 68 and is tapped into wall Bl. The bearing members 61- and 62 have shoulders it and l l, respectively, which can be and preferably are clamped tightly against adjacent faces of the intermediate frame I3 by screw t9, the gudgeons t and 66' being spaced slightly to permit this clamping. The gudgeons project beyond their shoulders a distance slightly less than half the width of bearing 69, see Fig 3.

A screw 12 is tapped through the forward part of intermediate frame ii in front of bearing 60 and is set up against flat surfaces 13-, Fig. 2, on the two gudgeons to prevent them from turning in the bearing 60 if it is not desired to rely wholly upon screw 69 to clamp the saddles in place. The latter screw holds the saddles together so that the single screw l2 can engage both surfaces 13. Rods l5 and i6 similar to pin 4!) may be provided for their corresponding shaft sections and ordinarily hold the shafts in their open bearings 83 and E i. When removed these pins 15 and 16 permit forward removal of the adjacent ends of their corresponding shafts.

The two saddles 6i and 62 are alike and each is symmetrical about a plane passing through the axis of its gudgeon and also the longitudinal axis of its slot bearing. The shoulders are formed like a horse shoe and their arm parts IT and 18. which define the slots are joined by a rounded part it, see Fig. 2. As shown in Fig. 3 one of the saddles has been inverted with respect to the other saddle in the direction of the length of the shafts 21 and 28 before being fitted to the frame I3.

If it be desired to remove shaft section 21 for instance its pin l6 will be removed and the left end thereof as viewed in Fig. 1 will be siid forwardly in the open slot bearing 6d then moved to the left so that its gudgeon iii may free itself readily from bearing it in the manner already described in connection with the removal of shaft section 28.

It may not be necessary in all instances to employ the set screw l2 as a supplement to the screw 53, but it has been found, desirable and when used will not require such a tight setting of the screw 69.

From the foregoing it will be seen that the invention sets forth simple mounting means for aligned cloth roll shafts of narrow ware looms, the bearing 4-5 as shown in Fig. 6 having tapered cups of non-circular cross section to receive similarly tapered non circular shaft gudgeons which free themselves from their bearings when the opposite ends of the associated shafts are moved forwardly. It will also be seen that the center bearing is made of two saddle bearings which are alike and one of which is inverted with respect to the other. Each of the saddles or hearing members BI and 82 has an open slot bearing extending along a gudgeon and wall positioned in the bearing 6!]. The walls 6? and are formed as parts of the gudgeons 65 and 6t and. the two saddles are joined by screw be passing through one wall and tapped into the other.

The center bearing shown in Figs. 2 and 3 is not claimed specifically herein but is made the subject matter of the parent application of which this is a division.

Having thus described the invention it will be seen that changes and modifications of the fort going specific disclosure may be made without departing from the spirit and scope of the inven tion.
